Igisabo kinyeganyega gifite igitandukanya cy’imigezi ibiri: Ikigega kimeze nk’igi kigabanyijwe kizengurutse igitandukanya, imigezi igahura kuri buri hengama

"Igikorwa gikorwa binyuze mu kunyeganyeza intebe C, iha ikigega cy’amavuta y’amata urugendo rwo guhengama rukurikirana, Igishushanyo 1, imirongo itukura, bityo bigatuma amavuta y’amata atemba vuba, agabanywa n’igitandukanya, mu migezi ibiri itandukanye mu nzira yayo, ihura ku iherezo ryayo, isimburana, bityo amavuta y’amata akagira igikorwa gikomeye kandi kidasanzwe gituma uduce tw’amavuta y’inka twihuta guhurira mu kirundo kimwe."

Capa ikigega kimeze nk’igi n’umupfundikizo ufite igitandukanya cyawo. Ikigega gikeneye ubuso bwo gucapiraho bufite nibura mm 210 z’uburebure. Capa muri PETG ku byiciro bya mm 0.2, kuzuza 30 %, inkuta 4; byoze mbere yo kubikoresha bwa mbere.

Ubaka umurandasi wa pine ufite uburebure bwa mm 220 hafi maze umanike intebe ya pine hagati y’inkingi zawo ku nkoni ya mm 10, ifite imirongo ibiri yo ku mpande yinjira mu biyobora by’ikigega. Manika inkoni y’icyuma hagati y’intebe ifite ikirundo cya ecrou nk’uburemere bwa pendulum.

Funga ibihumeka bibiri by’umupfundikizo n’aho ikigega gisohokera ukoresheje imfunguzo za cork.

Urupapuro rw’igishushanyo cya US 18,165, umutungo rusange (patenti yarangiye).

Reka amavuta y’amata afashe agere hafi kuri 15 °C, ugenzure na thermometre. Suka ml 600 maze ushyireho umupfundikizo ufite igitandukanya. Nyeganyeza intebe uva ku mpera ujya ku yindi uhoraho; bara igihe kugeza amavuta y’inka aje. Kuramo ikivuguto ku hasohokera. Sesa ikivuguto, wongeremo amazi akonje, uvuge gato maze wongere usese kugeza bisohoka bisukuye; vangamo agace k’umunyu maze upime amavuta y’inka.

**Daniel E. True** wo muri Lake Village, Belknap County, New Hampshire, US 18,165, 8 Nzeri 1857. Umurandasi we wari ufite uburebure bwa feet 2. Yanditse ko utuyunguruzo n’ibikubita bitobotse bitari bishya, avuga patenti za Enoch Thomas na John McLaughlin, maze asaba uburenganzira ku gitandukanya mu bisabo binyeganyega. Ikigega gicapwe ku gice cya gatatu cy’ingano ye, pine na ecrou bisimbura ibye. Ibicapwa bya FDM bigumana ibiryo mu mirongo y’ibyiciro byabyo, bityo byoze neza kandi ubisimbuze iyo byashaje.
